BACKGROUND OF THE INVENTION Field of the Disclosure

The present invention relates, in general, to wheeled devices forcarrying car seats.

Description of the Related Art

In the United States, the National Highway Traffic Safety Administrationsets guidelines for the use of car seats and all states have their ownlaws governing the use of car seats. For example, Texas requires thatchildren under 8 years old and less than 4 feet 9 inches tall be in acar seat or a booster seat. Children under 1 year old and/or less than35 lbs should be placed in a rear facing car seat when riding in anautomobile. California law also requires that children under 8 years oldand less than 4 feet 9 inches tall be in a car seat or a booster seat.Children under 2 years old that are less than 40 pounds or 40 inchestall must be restrained in a rear facing car seat.

Rear facing car seats typically can be used to carry an infant and therear facing car seat can be engaged with a detachable car seat base thatis properly tethered in a vehicle. Using such a system allows the parentto strap their small child in the rear facing car seat, carry the rearfacing car seat to the car, and engage the rear facing car set with thedetachable car seat base. Once the rear facing car seat is engaged withthe detachable car seat base, the rear facing car seat may not bedisengaged without toggling a release mechanism.

The car seat industry is always seeking improvements to car seats andthe different ways in which car seats are transported when not in amotor vehicle.

DETAILED DESCRIPTION

The following is generally directed to a rolling car seat carrier thatis suited to receive and engage a child car seat, e.g., a rear-facinginfant car seat. Embodiments are directed to a car seat carrier having acarrier body that is configured to receive and lockably engage an infantcar seat therein. The carrier body is further configured to retain theinfant car seat in engagement with the carrier body until a releasehandle on the infant car seat is toggle by a user. As such, the infantcar seat is securely attached to the carrier body. The carrier body caninclude two front wheels directly attached to the carrier body. The twofront wheels can rotate around a first axis and swivel around a secondaxis. The carrier body can also include two rear wheels directlyattached to the carrier body. The two rear wheels can rotate around afirst axis. A pivoting and telescoping handle can be attached to thefront of the carrier body near the front wheels. A user can grasp ahandgrip on the pivoting/telescoping handle with one hand and push thecar seat carrier or pull the car seat carrier. Accordingly, the car seatcarrier is human powered and not powered by a motor, an engine, or othernon-human power source.

The pivoting/telescoping handle is configured to be move between variouspositions. For example, the pivoting/telescoping handle can be moved toa first stowage position in which the pivoting/telescoping handle is ina collapsed configuration and folded back across the carrier body of thecar seat carrier. Further, the pivoting/telescoping handle can be movedto a second stowage position in which the pivoting/telescoping handle isin the collapsed configuration and rotated away from the carrier body sothat the hand grip on the pivoting/telescoping handle is in a positionfurthest from the carrier body. The pivoting/telescoping handle can alsobe moved to a front push/pull position in which the pivoting/telescopinghandle is in an extended configuration and rotated so that thepivoting/telescoping handle, or the handgrip, is forward of the axisaround which the pivoting/telescoping handle rotates. In this frontpush/pull position, a user can use the pivoting/telescoping handle topush the car seat carrier or pull the car seat carrier. In either case,an infant car seat, and an infant securely placed in the infant carseat, would be facing the user.

The pivoting/telescoping handle can be further moved to a rear pushposition in which the pivoting/telescoping handle is in the extendedconfiguration and rotated so the pivoting/telescoping handle, orhandgrip, is behind the axis about which the pivoting/telescoping handlerotates. In this position, a user can push the car seat carrier with theinfant car seat engaged with the car seat carrier, and an infanttherein, facing the direction in which the car seat carrier is pushed,i.e., away from the user. Finally, the pivoting/telescoping can be movedto a broadcast position in which the handle, in either the collapsedconfiguration or extended configuration, is rotated to a verticalposition or slightly aft so that the handgrip is behind the axis ofrotation. In the broadcast position, a portable electronic device, e.g.,a smartphone, that is securely held within a bracket on thepivoting/telescoping handle can be located in a position to allow aninfant within the infant car seat to listen to and watch content that isbeing broadcast by the portable electronic device.

The car seat carrier is configured to have a foot print that is nearlyidentical in area to the footprint of the infant car seat that can beinstalled therein. As such, the car seat carrier takes up relativelylittle floor space and is very easy to maneuver in crowded spaces, innarrow spaces, around closely placed objects, etc. Further, the car seatcarrier supports the infant car seat in a manner that is relatively lowto the surface on which the car seat carrier is used. This provides arelatively low center of gravity that makes is difficult to tip over thecar seat carrier. Further, this allows a user to sit in a chair adjacentto the car seat carrier, e.g., at a doctor's office, and easily see andinteract with the infant that is securely placed within the infant carseat attached to the car seat carrier.

FIG. 1 through FIG. 14 illustrate a car seat carrier that is generallydesignated 100. As shown, the car seat carrier 100 can include a carrierbody 102. The carrier body 102 can be sized and shaped to receive andlockably engage a complementary shaped infant car seat, as described indetail below.

Ina particular aspect, the wheel 238 may be made from a polymer material.In particular, the wheel 238 may be made from polypropylene, such asimpact grade polypropylene or impact copolymer polypropylene. In anotheraspect, the wheel 238 may be made from nylon. The tire 240 may also bemade from a polymer material. For example, the tire 240 may be a solidtire made from polymer foam material. Further, the tire 196 maypolyurethane foam material, e.g., a closed cell polyurethane foammaterial. In another aspect, the tire 240 may be made from rubber andfilled with air. In still another aspect, the tire 240 may be a solidpolymer tire, e.g., a solid polyurethane tire or a solid rubber tire.Since the wheel 238 is mounted on the axle 234 of the wheel supportframe 232, the wheel 238 and the tire 240 may also rotate three-hundredand sixty degrees (360°) relative to the carrier body 102 with the firstfront wheel assembly 210.

FIG. 4 indicates that the first front wheel assembly 210 may alsoinclude a wheel lock 242 that may be toggled between an “ON” positionand an “OFF” position. When the wheel lock 242 is in the “ON” position,the wheel 238 and the tire 240 may not easily rotate within the firstfront wheel assembly 210 on the axle 234. When the wheel lock 242 is inthe “OFF” position, the wheel 238 and the tire 240 may freely rotatewithin the first front wheel assembly 210 on the axle 234. Accordingly,a user can lock the wheel 238 of the first wheel assembly 210 in orderto prevent the car seat carrier 100 from freely moving relative to asurface on which the car seat carrier 100 is placed.

FIG. 2 shows that the second front wheel assembly 220 can include a baseplate 250 from which the threaded stem 222 can extend up into carrierbody 102 through the bottom plate 150. A wheel support frame 252 can becoupled to the base plate 250 via a bearing assembly and an internalpost (not shown). The wheel support frame 252 can rotate three-hundredand sixty degrees (360°) relative to the base plate 250 around an axiscentered on the threaded stem 222. Further, the wheel support frame 252can rotate around the axis centered on the threaded stem 222three-hundred and sixty degrees (360°) relative to the carrier body 102.

The second front wheel assembly 220 also includes an axle 254 mounted inthe wheel support frame 252. The axle 254 can be an at least partiallythreaded bolt held in place within the wheel support frame 252 by athreaded nut 256. A wheel 258 can be mounted on the axle 254 and rotatethereon. Further, a tire 260 can be mounted on the first front wheel258. In a particular aspect, the wheel 258 may be made from a polymermaterial. In particular, the wheel 258 may be made from polypropylene,such as impact grade polypropylene or impact copolymer polypropylene. Inanother aspect, the wheel 258 may be made from nylon. The tire 260 mayalso be made from a polymer material. For example, the tire 260 may be asolid tire made from a polymer foam material. Further, the tire 196 maypolyurethane foam material, e.g., a closed cell polyurethane foammaterial. In another aspect, the tire 260 may be made from rubber andfilled with air. In still another aspect, the tire 260 may be a solidpolymer tire, e.g., a solid polyurethane tire or a solid rubber tire.Since the wheel 258 is mounted on the axle 254 of the wheel supportframe 252, the wheel 258 and the tire 260 may also rotate three-hundredand sixty degrees (360°) relative to the carrier body 102 with thesecond front wheel assembly 220.

FIG. 4 indicates that the second front wheel assembly 220 may alsoinclude a wheel lock 262 that may be toggled between an “ON” positionand an “OFF” position. When the wheel lock 262 is in the “ON” position,the wheel 258 and the tire 260 may not easily rotate within the secondfront wheel assembly 220 on the axle 254. When the wheel lock 262 is inthe “OFF” position, the wheel 258 and the tire 260 may freely rotatewithin the second front wheel assembly 220 on the axle 254. Accordingly,a user can lock the wheel 258 of the second front wheel assembly 220 inorder to prevent the car seat carrier 100 from freely moving relative toa surface on which the car seat carrier 100 is placed. It can beappreciated that the wheels 238, 258 of both front wheel assemblies 210,220 may be locked at the same time to prevent the car seat carrier 100from rolling on a surface.

It can be appreciated that the front wheels 238, 258 and front tires240, 260 can swivel around the stems 212, 222 in unison with each other,but also independent from each other. Further, the front wheels 238, 258and front tires 240, 260 can swivel around the stems 212, 222 inresponse to steering inputs provided to the front 106 of the carrierbody 102 via handle affixed thereto, as described in detail below.However, the front wheels assemblies 210, 220 are not directly connectedto the handle.

As shown in FIG. 2, the rear wheel assemblies 180, 184 can have adiameter, D_(R). The front wheel assemblies 210, 220 can have adiameter, D_(F). Further, the car seat carrier 100 can have a firstwheelbase when it is pulled, WB_(PULL), and a second wheelbase when itis pushed, WB_(PUSH), as illustrated in FIG. 13.

With the configuration of structure described herein the car seatcarrier according to any of the aspects, can provide a car seat carrierthat is relatively low to the ground with a relatively low center ofgravity. This can provide a car seat carrier that is difficult to tipover. Further, this can provide a car seat carrier that a user can seeinto and keep an eye on an infant therein while sitting in a chair,couch, or other low seating element. Moreover, while seated, a user cangently roll the car seat carrier back and forth to provide soothingmotion for an infant placed in an infant car seat engaged with the carseat carrier. Additionally, the configuration of structure describedherein, can provide a car seat carrier that is relatively compact andcan fit in areas that traditional strollers, or car seat carriers,cannot fit. For example, the car seat carrier according to one or moreaspects herein can fit in the aisle on a bus, a train, an airplane, orother narrow aisle. Further, the car seat carrier can fit on a subwaycar without taking up much more space than a car seat that may becarried by a user. In another aspect, the car seat carrier can fit intothe overhead compartment on most passenger airplanes. The car seatcarrier according to one or more embodiments described herein canprovide a car seat carrier that is human powered and non-motorized.Further, the placement of the wheels and handle results in a car seatcarrier that is very agile, nimble, and relatively easy to maneuveraround obstacles and in locations that may be difficult to maneuver atypical stroller. For example, the car seat carrier is relatively easyto push or pull on a sidewalk, around light posts, around mailboxes,around clothing racks in a store, inside a house, or at other locationsthat are filled with obstacles that hinder the use of a conventionalstroller. Further, the bi-directional usability of the car seat carrierprovides a car seat carrier that can be easily pushed or pulled. Inaddition, the placement of the wheel assemblies relative to each otheron the carrier body of the car seat carrier provides a car seat carrierthat can quickly be rotated from the push position to the pull position.As such, if a user is pushing his child in an infant car seat lockablyinstalled within the car seat carrier and the sunlight is shining in thechild's face, the user can quickly rotate the car seat carrier, and theinfant car seat therein, one-hundred and eighty degrees (180°) from thepush position to the pull position so that the sunlight is no longershining in the child's face.

Additionally, the car seat carrier, according to one or more aspectsdescribed herein, provides a relatively easy way to transport an infantcar seat to an automobile or other vehicle. At the vehicle, the user candisengage the infant car seat from the car seat carrier and engage theinfant car seat with a detachable car seat base properly installedwithin the vehicle. To stow the car seat carrier in the vehicle trunk,or other space, the user can simply move the pivoting/telescoping handleto the collapsed configuration and rotate the pivoting/telescopinghandle to the first stowage position, i.e., so that thepivoting/telescoping handle is folded back over the top of the carrierbody. The user may then easily lift the car seat carrier and place it inthe trunk of the vehicle for storage. To prevent the car seat carrierfrom rolling around within the trunk of the vehicle, the front wheelassemblies can be locked. When the user arrives at his or herdestination, he or she can easily lift the car seat carrier from thetrunk of the vehicle, rotate and extend the handle to the push/pullposition, release the infant car seat from the detachable car seat basein the vehicle, and engage the infant car seat with the car seatcarrier. Using the car seat carrier is quite easy. There is no need tocollapse or expand a mechanically complex framework that is typicallyassociated with a folding stroller. Many folks will leave theirconventional folding stroller at home because it can be relativelydifficult to fold and unfold. Also, a conventional folding stroller canbe relatively bulky, heavy, and difficult for some smaller users to pickup and easily place the folded stroller in the trunk of a vehicle.

Moreover, since the car seat carrier is specifically designed to receivethe infant car seat in a manner similar to that of the detachable carseat base, the infant car seat is securely locked within the car seatcarrier and the risk of the infant car seat from falling out of the carseat carrier is minimized. Further, using the car seat carrier,according to one or more of the aspects described herein, in conjunctionwith an infant car seat carrier provides a very safe way to transport aninfant child that is properly buckled in the infant car seat. Mostinfant car seats are crash tested and are designed to withstand carcrashes while protecting the infant therein. If a user is pushing his orher child around the neighborhood, in a parking lot, or other location,and the infant car seat carrier assembly is impacted by a motor vehicle,a bicycle, or other vehicle, the child is less likely to get injuredwhen compared with a conventional stroller or conventional wagon whichis not as rigorously tested as a car seat and is not designed to survivean automobile accident. It can be appreciated that the car seat carriercan be integrally formed with the infant car seat.
